has issued an update to the 4.01 M33-compatible plug-in, fixing numerous bugs along with adding support for UMD disc titles. Additionally, savestates can now be created on a per-game basis.
Keep in mind that PSPStates is compatible only with Slim units currently, due to increased memory usage.

* Fixed important bug in inter-thread code (semaphore wasnââ‚¬™t waiting due to interrupts disabled), that caused the load state to not be completely read in some cases. This caused black screen after state load (unless you just saved that state, in this case state was still in ram), or even worse, game not working properly due to partial load.
* Added states per game basis. The controls are slightly different: old controls now do a local savestate/loadstate of the game, while pressing additionally select button will save/load a global state. See instructions for more info.
* Fixed bug that caused normal sleep mode waking up inmediately.
* UMD discs and isos in normal UMD mode are now supported. However, they require to nullify UMD cache, by flashing one file. For details on this process, refer to the readme file.
